ErdasIMG: Conversion between LAN or GIS (Erdas) files and IMG
Direct access to online help: ErdasIMG
Access the application from the menu:
"File | Import | Rasters | LAN/GIS (Erdas 7.4) -> IMG"
"File | Export | IMG -> LAN/GIS (Erdas 7.4)"
Presentation and options
This program allows putting several IMG files into one Erdas file of type LAN or GIS. On the other hand, it can also extract all the image bands contained on a LAN file and save them into different IMG files. GIS files only have one band and they are usually thematic files, not radiometric images.
Header information:
Shows information about the Erdas file header in an ordered way.
Conversion Erdas -> IMG:
Converts Erdas files of LAN or GIS type into IMG files. For LAN files, the number of IMG files will depend on the number of bands contained in the ERDAS file. Run this application with option 0 to obtain this information. For GIS files, if no TRL file is found, no palette will be written (the Fitxer_P25 name is ignored).
Conversion Erdas -> IMG (with P25 palette):
Converts GIS Erdas files into IMG, with an explicit output P25 file.
Conversion IMG -> Erdas:
Puts several IMG files into one Erdas file of LAN or GIS type.
Conversion IMG -> Erdas (with P25 palette):
Converts IMG files into a GIS Erdas file, with an explicit input P25 file.
In the conversion from GIS to IMG, if a TRL file, containing the color palette and the class names, exists, a file P25 with the palette will be created; class names are stored in the DOC file.
In the conversion from IMG to GIS, DOC file categories are written into the TRL file, as well as palette colors, that are extracted from the P25 file given at the command line.
This program runs with Erdas files version 7.4 .
The Erdas format is appropriate to work with Erdas, Arc/Info and
ArcView.
